Really i've always thought it to be litres???:confused:

Right now i've only got glass breakages and drinking the metal salt solution. Surely the voltage produced isn't enough to shock anyone? thanks

Hello, does anyone know what this experiment is about? We even get to do it in class! thanks

lol i know a method to copy the docs

lol i don't even know my exact values, i just use a calculator.

ok then lol. but the working seems so pintless!

o cool thanks word.! lol one last question: Without the aid of tables find: a) sin-1sqrt(3)/2 are you allowed to use a calculator?

o i have another 2 questions: Find functions which are the inverse of each of the following. State the domain and range of the inverse in each case. 1) f(x)=sqrt(9-x2) for -3<=x<=0 ================================================ 2) is it possible to find the domain and range of a function...

yep tanks

oh bugger, i get it now. i think it helps to draw the diagram now actually thanks.

Find functions which are the inverse of each of the following. State the domain and range of the inverse in each case. a) f(x)=2-x, x>0 b) f(x)=x2+2x, x_>0 for the first one i got f-1(x)=(-lnx)/(ln2) with D: x>0, R: y>0 and the second one i got f-1(x)=-1+sqrt(x+1) with D: x_>-1, R: y_>0 thanks

oic, thanks shifty

ok, but that much? wow

oh ok but which way are the squares stacked?

lol what does the diagram look like first?

Do we have to know the background info on the Haber process? e.g the production of nitrogen/hydrogen and what reaction vessel/conditions the process takes place in? thanks:confused:

not for me, i'm dumb lol

Oh bugger, i screwed the bounds. thanks pluvia

Question: Evaluate 2∏∫2 to 0 (xe-x2)dx thanks

The natural display one (fx82AU) is the best
